UNITED STATES NORMAN N. RANKOW, OF NEW YORK, Y.

1 'roBAoco PIPE.

Application filed February 14, 1921. Serial No. 444,760.

To all whom it may concern:

Be it known that I, NORMAN N. RANKOW,

a subject of Great Britain, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Tobacco Pipes, of which the following is a specification.

My said invention relates to a new and improved tobacco pipe and it is an object of the invention to produce a pipe which shall be cool and pleasant to the taste, preventing access of heat and the products of combustion to the mouth of the user.

It is a further object of my invention to provide a pipe in which either a large or a small quantity of tobacco can be used with equal, facility and from which the residue of burnt or unburnt tobacco may be readily removed without striking the pipe against hard surfaces by which it is liable to be damaged.

Referring tothe accompanying drawings whichare made apart hereof and on which similar reference characters indicate similar parts, I

Figure 1 is avertical sectional view, Figure 2, a detail showing the two separating plates whereby the'tobacco is kept separate from the filtering material in the bottom of the pipe, and

Figure 3, a detail showing the cooling tube used in the stem in end and side view.

In the drawings 10 indicates the upper member of the bowl whichissecured to the lower member 11 by screw threads indicated at 12. Between the upper and lower members is a perforated metallic plate 13 which is held securely in position, as by screwing the upper member down on the lower. I may form the perforations of various sizes and in various patterns. Underneath the separator plate is a filter of cotton wool 14 which removes the nicotine and coal tar from the smoke and thereby makes the smoke cooler and pleasanter tothe taste as well as preventing biting of the tongue. This filter is easily replaced by a fresh change of cotton wool when desired. The separator plate, which is preferably made of tin, also takes part in the cooling action.

The stem 15 is of usual construction exceptthat I enlarge the bore of the same at a part of its lengthas at 16, the bore of the lower bowl member being correspondingly enlarged at 17 toaccommodate a tube 18 preferably made of aluminum. At the end farthest from the bowl this tube preferably is crimped as shown in Figure 3 of the drawings to .stop any fragments of tobacco or other material that may attempt to pass through thestem. 1

I haveshown in Figure 2 a similar separator plate 19 which is intended to fit closely within the lower bowl member and which is to be used when a full charge of tobacco is'desired. It will be seen that with the plate 13 in place the pipe will hold only about one-half of a normal charge. By

placing the small separator 19 011 the cotton and forcing it down I am enabled to nearly double the quantity of tobacco without losing to a material degree the, desirable re sults produced by the combination of elements.

Various modifications of my device will suggest themselves to Wood-workers and others skilled in the art and therefore I do not limit myself to the specific device shown 1n the drawings and described in the specificpt on but only as indicated in the appended c aims.

Having thus fully described my said in 'vention, what I claim as new and desire to secure by Letters Patent, is:

.1. In a tobacco pipe, a lower bowl member, filtering materialin said bowl member,

a perforated plate on said filtering material, an upper bowl member and a second perforated plate clamped between said upper and lower bowl members, substantially as set forth.

2. In a tobacco pipe, a lower bowl member, filtering material in said bowl member,

.- a perforated plate on said filtering material,

an upper bowl member and a second perforated plate clamped between said upper and lower bowl members, said second perforated plate being adapted to be removed in order to accommodate a larger charge of tobacco, substantially as set forth.

In witness whereof, I have hereunto set my hand and seal at Washington, District of Columbia this eighth day of February, A. D. nineteen hundred and twenty-one.
